SAN DIEGO - A San Diego man reportedly groped a woman at Saturday's Beyonce concert, and when her companion objected, bit the end of the boyfriend's finger off.
Roberto Alcaraz-Garnica, 25, remained jailed Sunday for a likely sex offense.
He was arrested at the Rose Bowl on suspicion of sexual battery and mayhem, which is alleged for the disabling or disfiguring of another person, the Pasadena Star-News reported.
Alracrez-Garnica grabbed a woman's breast, and bit off her boyfriend's fingertip in the ensuing tussle, according to a police statement to the Star-News.
Jail records show he is still held in lieu of a $100,000 bail.
About 55,000 people attended the sold-out concert at the Rose Bowl Saturday, and police arrested eight alleged drunks and two scalpers.
A second concert was scheduled for Sunday.
